BIOSENSORS' PREPARATION TO BE USED FOR ENTRAPMENT METHOD WITH COPOLYMERS POLYANILINE DERIVATIVES

The entrapment method was used to prepare electrochemical biosensors. Using controlled potential method, copolymers were synthesized between aniline y sulfonated-anilines in aqueous media at pH 4.9 on Platinum disc. The copolymers were characterized by elemental analysis and spectroscopy. Glucose-ox...
